Development of a method for the online estimation of the permanganate index of water entering water treatment facilities

Summary

The paper dwells upon the development of a method for the online estimation of the quality of water supplied to water treatment facilities. A composite index is proposed co-charactering both the input parameter of the indirect estimation of water quality and the permanganate index. It is shown that the proposed composite index has a minimum from the Raman scattering signal. The magnitude of Raman scattering is calculated upon the composite index reaches a minimum. It is shown that the permanganate index can be represented as a sum of two components, where the first component is determined by fluorescent radiation, and the second one by the previously calculated optimal value of the Raman radiation. An extrapolation method for determining DOM or CDOM with a known value of one of these indices is proposed based on the linear relationship constructed between them.
